HAN GER-SOCKET.

Specification of Letters Patent.

Patented Mar. 1?, 12914.

Application filed January 2'7, 1910. Serial No. 540,374.

To all whom it may concern Be it known that I, FRANK N. KNnAs, a citizen of the United States, residing at Norristown, Montgomery county, Pennsylvania, have invented certain new and useful Hanger-Sockets, of which the following is a specification.

Whether hangers be of heavy orilight construction, and whether they be provided with separate sockets or not, depend in large measure upon the character of the that it would at once be evident in the mind of the expert in that art that it would apply to many other forms with which he was familiar.

One of the purposes of my invention is to provide a space which is free from concrete above the socket, in line therewith, and to secure this end by means supported directly upon the socket or upon some part intimately associated therewith.

A further purpose of my invention is to.

secure the hanger or socket or hanger socket to the mold board bymeans preferably capable of insertion from above the mold board by unskilled labor, and of removal by like labor from beneath it; a matter of convenience at all times, and rendering it possible to withdraw this holder from the concrete while the latter is green with advantage because of the character of the holder. I further provide for the projection of a pin or other suitable member through they socket and above it either to act as a guard against undue encroachment of concrete, or

to support a collar or cap for this purpose.

Where the projection is itself the guard it may be made to core the space. I prefer to make such a projecting pin continuous with the part which holds the hanger socket to the moldboard, by which part, also I provide for initial retention to the hanger or hanger socket of a protective sheet, plate, washer, disk, or other protective facing preferably mounting the facing upon the part these other functions.

permissibly performing either or both of The character of the protective facing, where one is needed, will vary with the kind of destructive influence feared in that building, whether fire, acid, alkali, rust, or other kind.

Where the guard against concrete encroachment at the top is preferably independent of any plug, pin or other like member, it is most desirably mounted upon the socket itself, so that in my preferred form both the concrete spacing guard at the top and the protective facing are used, and both are initially connected with the hanger or hanger socket for shipment and placing.

The several features of my invention recited are independent of the character of socket used, whether it be the lower bar or part of the hanger, suitably threaded or otherwise adapted for connection to outside parts, or a separate socket supported upon the hanger, or a combination of these forms.

A further feature of my invention, shown in the splitting of the dowel pin which I may use, is also independent of the charaoter of socket. Other forms of pin, also, can be split.

In the drawings: Figure 1 is a vertical section through a hanger socket, retaining and protecting devices and mold board illustrating one form of my invention. Fig. 2 is a top plan view of the structure seen in Fig. l but omitting the mold board. Fig. 3 is a bottom plan view of the structure illustrated in Fig. 1 but omitting the mold board. Figs. 4: and 5 are vertical. sections of sockets showing modified forms of concrete-spacing de vices. Figs. 69 and 11-13 are vertical sections of a variety of forms of hangers, sockets, concrete-spacers, hanger protectors and retaining devices by which I illustrate my invention. Fig. 10 is a section upon line X-X of Fig. 9. Fig. 1 1 is a section upon line YY of Fig. 12. i

I have selected my illustrations of hangers etc. from forms which have proved to be cheap, practical and effective.

The length of the bolt, here taken as the typical form, by which outside connection is ultimately to be made with one of the hangers or sockets is, of course, not known in advance, nor does the one selecting it always know the extent of the thread in the socket. Hence space must be provided for projection of the bolt through the socket,

which is preferably made by a guard to keep the concrete away from the socket. I make use of a different form of guard, or a guard differently mounted from that of other patentees. The hanger socket must also be secured to the mold board and I prefer to protect the otherwise exposed face of the hanger socket by novel means.

Considering the figures in detail, in Figs. 1, 2 and 3 I have shown a hanger 1 of general U shape and of uniform thickness, upon whose base 2 I rest a socket in the form of a nut 3, in this case recessed cylindrically at l to receive a cover 5 of desired height. The cover is held in place, in this form, by a flange 6 upon it and by any suitable calking 7. Nuts counterbored in this manner are well known. In the form shown in Fig. 4 I show a somewhat similar counterbored nut 3 in which a cover 5' is driven. In the form shown in Fig. 5 I have shown a plain nut 3 that is, not counterbored, but provided with an outer ring upon which is sprung or compressed a cover 5 Again considering Figs. 13 particularly, both the hanger and the nut or socket are threaded so as to offer an extended surface for engagement by the bolt, suitable for heavy service if the normal size of each be maintained, or making possible the use of thinner materials for the hanger to secure the same strength. The threading upon the hanger can here be omitted.

Beneath the hanger or yoke I place a plate or sheet of facing material such as S, which is preferably nonabsorbent or but partly absorbent, and which is proof against injury 'by fire, acid and alkali, in order that the socket may thus be fully protected. Such a material is found in commercial forms of asbestos and in a variety of compositions of general cement composition, as well as in a number of other materials, particularly so-called insulating materials. I show it substantially in the form of a washer and with the edge chamfered as at 9, so that the concrete shall itself grip and retain this facing. Where the facing initially used is intended for spacing purposes only, to be removed with the mold board, the chamfering is preferably reversed, as in one of the other figures.

In the form shown on sheet 1 I make use of a pin for a multifold purpose, to retain the parts of the hanger socket in fixed relation for shipment, handling and placing upon the mold board, to secure it to the mold board, and permit its removal therefrom from beneath the board, and, if it be desired to use a very thin cover 5, to support this against excessive pressure. While there is cooperation between the structures and functions making the multifold purposes stated possible, it is evident that they are also each valuable separately. Whether the forms of hanger cover, face protector and pin operate together or separately the form and material of each may be greatly varied while still cooperating with the others.

The projection of the pin above the socket or hanger may itself guard against concrete encroachment, or form the main or only support for a guard for that purpose.

I prefer to make the pin 10 from a plain cylindrical strip of wood, such as can be purchased commercially in any lengths for dowel purposes, and to place what little thread there need be upon it by the act of screwing it into place. I prefer to split or kerf the pin for any desired distance, showing the slitting at the top in F ig. l and stopping it there before it passes through the mold board. This kerfing makes the top compressible to reduce its diameter and gives advantage from the spring of the material. I project the top of the pin at 12,

Figs. 1, 6 and 8 and use it as additional support for cover 5, as main support for collar 5 which could be a cover if desired, resting wholly upon the pin if necessary, or make it the actual coring means as in Fig. 8.

The lower part of the kerf is shown at 13 beneath the protective facing so that an implement can be inserted to give purchase for screwing the pin into and out of position. The lower part of the pin is preferably driven through the mold board far enough for the projecting part to be gripped in any suitable manner to unscrew the pin from below in the more usual and desirable form'of use of my invention, either before or after the concrete has set sufficiently to permit the removal of the mold board. There is considerable advantage in removing it while the concrete is green where a bare pin at the top is used as the concrete does not attach so firmly to it then. However, oiling the top assists in'preparing for removal. The mold board 15 is of any suitable form.

In Fig. 6 I have shown the tops of the walls of the hanger 1 as flanged at 16 for further engagement with the concrete. Here the cover 5 is in the form of a screw collar supported largely if not entirely upon the projecting part of the pin and open at the top at 17. Here I show a pin 10 with an enlarged base passing through the board 15 as seen at 14: Above the board it forms a shoulder 18 upon which is rested a protective and spacing collar 19 partially closed at 20. This can be made of metal which is inert to any fumes or liquids from which protection is desired. Usually copper is best for it.

In all of the forms where the threaded aperture is itself in danger of injury because of its exposure, it can be readily plugged with wood or' closed or protected by other means. i

In Fig. 7 I have shown spread Walls for the hanger 1 with a cover 5 and a preferably machine screw 21 headed at 22 within a washer 8 chamfered as at 9. The cover is driven into an aperture 23 in a thickened base 2 so that no separate socket is needed. The base is threaded as seen, the whole forming a very desirable form of hanger with convenient retaining devices, including nails 24, except that it cannot be controlled in any manner from below the mold board.

In Fig. 8 the hanger 1 having base 2 is provided with socket 3 and is preferably screwed upon a pin 10 slitted to 13 and driven up from below the board leaving the bottom of the pin 14 projecting. It may be prevented from turning, if this be necessary, by bar 14 engaging a nail in the board.

In Figs. 9 and 10 the compound or composite hanger shown is made up of substantially parallel U shaped strips 25 united by 'crosspieces 26 and supporting a socket in the form of a bar 3 within which pin 10 is preferably screwed from below. The pin is then spread into suitable firm contact with the walls of the hole in the board by any means such as nail or spike 27. It could be fastened transversely instead of by spreading, or could have a nut upon its lower part.

In the formshown in Figs. 11, 12 and 13 cylindrical hangers 1 1 and 1 are shown with bases 2 2 and 2 Base 2 supports a socket 3 circularly grooved at the top at 28 and projected at the bottom at 29. The

sleeve 5 rests in the groove and supports the plate 30. The lower end 31 of the pin 10 is slitted and driven into the board, while the upper end is threaded as at 32. 1 is flanged through a part of its circumference, at least, as at 33 to be retained upon the board by a double pointed nail having semicircular yoke 84 beneath projections 35 upon the hanger and having nail ends 36. The base 2 of this form constitutes the socket. y

In the form shown in Fig. 13 the socket is engaged by a metal screw 10 pointed at 37 and the top of the hanger is closed by a plug 30.

I have illustrated a sufiicient number and variety of forms of my invention to indicate that the claims are entitled to a reasonable range of equivalents in their interpretation.

What I claim as new and desire to secure by Letters Patent is:

1. In a device of the character stated an apertured flat base, a threaded socket resting thereon, upwardly extending spaced wings, separated throughout their lengths, attached to the outer edges of the said base, said base being wider than the socket so that the wings are spaced beyond the socket, permitting plastic material to surround the socket and engage with the inner faces of the wings, a pin passing through the aperture of the base, engaging the socket and passing above the socket to core the material within which the device is placed, and means upon the lower portion of the pin adapted to engage with a mold board.

2. In a device of the character stated, an apertured fiat base, a threaded socket resting thereon, upwardly extending spaced wings, separated throughout their lengths, attached to the outer edges of the said base, said base being wider than the socket so that the wings are spaced beyond the socket permitting plastic material to surround the socket and engage with the inner portions of the wings, and a cap carried by and entering a recess in the upper part of the socket and secured to the socket by the engagement with the inner walls of the recess.

3. In a device of the character stated, an apertured flat base, a threaded socket resting thereon and having its upper surface exposed, upwardly extending spaced wings, separated throughout their lengths, attached .to the outer edges of the said base, said base being wider than the socket so that the wings are spaced beyond the socket permitting plastic material to surround the socket and engage with the inner faces of the wings, a pin passing through the aperture of the base, engaging the socket, and means upon the lower portion of the pin adapted to engage with a mold board.
